Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of digital printers, and in particular to an operating method of a digital printer that automatically completes a printing process by scanning a two-dimensional code. Background Art
[0002] Traditional carton production equipment uses engraving printing to carve text on the convex surface of the offset plate and stick the offset plate on a drum; when the drum passes over the ink cartridge, the convex surface of the offset plate (the outline of the text) is sticky with ink, and when the drum passes over the cardboard below, the convex surface of the offset plate prints the ink on the cardboard, displaying the text and completing the printing.
[0003] The digital printer uses a plateless printing method. The nozzle is located above the paper feed belt. The suction fan adsorbs the cardboard on the paper feed belt. When the belt rotates, the cardboard passes under the nozzle, and the digital nozzle sprays ink to print text and patterns on the cardboard. There is no need for engraving, which reduces costs and improves production efficiency.
[0004] Before printing, the existing digital printers need to copy and download the printed PDF image file to the host computer (a computer), and then call the Ruitu RIP software to convert the image file into raster dot matrix data (PRN file), and then transfer the PRN file to the board of the lower computer (printing host) to control the ink discharge of the nozzle and spray the image on the cardboard. The above printing process is complicated and requires an independent operator to operate the printer and complete the above process manually.
[0005] Currently, some digital printing software on the market provides a QR code scanning function, but the QR code only contains the carton size and does not contain the URL address of the PDF print file. This means that the sharp image processing of the PDF print file still needs to be done manually on the host computer, which is time-consuming and labor-intensive.
[0006] The present invention provides a new method that allows workers to scan the code with one click, and the digital printer automatically completes all the above processes and prints the pattern on the carton, which facilitates the operation of the equipment and improves the production efficiency. Summary of the invention
[0007] The object of the present invention is to provide a method for improving the printing efficiency of a digital printer and facilitating the operation of the machine.
[0008] The purpose of the present invention can be achieved through the following technical solutions: The present application provides a method for improving the efficiency of a digital printer, comprising the following steps: 1. In the client program, the user enters the size and quantity of the carton, uploads the PDF print file, and submits the carton order to the server; 2. The server receives the carton order, stores the PDF file uploaded by the user in the server's specified directory, and gives a URL address; 3. The factory selects the order in the backend production management system and prints the production work order. The work order contains a QR code, which is generated by the server and contains the URL address of the PDF file. 4. A barcode scanner is installed on the upper computer of the digital printer. The barcode scanner is used to scan the QR code on the production work order. The upper computer then obtains the size and quantity of the carton and the URL of the storage address of the PDF file on the server; 5. The host computer accesses the URL of the PDF file, downloads the print file from the server to the local computer, and saves it in the hot directory of the Ruitu software; 6. The Ruitu software monitors the hot directory. When a new PDF file is found in the hot input directory, it will automatically load the PDF file, convert it into raster dot matrix data (PRN file) recognizable by the printer, and store it in the specified hot output directory; 7. The upper computer monitors the thermal output directory. When it finds that the PRN file has been generated, it outputs the PRN file to the board of the lower computer for paper feeding and printing.
[0009] Furthermore, the server URL address of the PDF file can use a short URL to fix the length of the URL string, which is convenient for software processing.
[0010] The beneficial effects of the present invention are: The QR code of the production work order contains the URL of the PDF file, so that the host PC of the digital printer can obtain the URL of the PDF after scanning the code and download it to the hot directory of the Ruitu software. The Ruitu software will automatically convert the PDF into raster dot matrix data (PRN file), and then transfer the PRN file to the board of the digital printer to complete the printing.
[0011] During the entire printing process, the operator only needs to scan the QR code, and the digital printer can automatically complete the sharp image processing and print the graphics on the cardboard; compared with the existing printing method, this patented method is more convenient and faster, and reduces printing costs.
[0012] In order to further explain the technical means and effects taken by the present invention to achieve the predetermined invention purpose, exemplary embodiments will be described in detail here, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples of methods and systems consistent with some aspects of the present application as detailed in the attached claims.
[0013] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The singular forms of "a", "said" and "the" used in this application and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.
[0014] The specific implementation methods, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0015] Figure 1 to Figure 7 A circuit diagram for the technical implementation of a fool-proof digital printer.
[0016] The user first uses the mini program client (see Figure 2 ), enter the box size, production quantity, upload the PDF print file, and submit the carton order; the server receives the carton order submitted by the user and stores the PDF file in the specified directory of the server.
[0017] The factory checks the order in the back-end production management system (see Figure 3 ), and print the production order (see Figure 4 ), the QR code on the work order is generated by the server. The QR code includes the size of the carton and the URL address of the PDF file on the server.
[0018] Furthermore, the server URL address of the PDF file can use a short URL, which can reduce the number of characters in the URL, and the length of the string is fixed, which is convenient for the scanning software to quickly analyze and process the string received by scanning the QR code.
[0019] On the digital printer's host PC, set up the Ruitu software and specify the input and output hot directories (see Figure 5 ), the Ruitu software monitors the input hot directory. When a new PDF file is found in the directory, it will perform Ruitu processing on the file, convert it into raster dot matrix data (PRN file), and store the PRN file in the output hot directory.
[0020] The digital printing software is installed on the host PC of the digital printer. Click the "Scan Code to Print" button, and a dialog box will pop up. Use the barcode scanner installed on the host computer to scan the QR code on the production work order. The printing software scans the code to obtain the carton specifications and the URL address of the PDF file on the server.
[0021] The printing software accesses the URL address, downloads the PDF file to the input hot directory of the Retu software, and then waits for the Retu software to perform the Retu RIP conversion, converts the PDF file into raster dot matrix data (PRN file), and stores it in the output hot directory (see Figure 6 ).
[0022] When the printing software finds that the PRN file has been generated, it transfers the PRN file to the lower computer board of the digital printer, and the board drives the print head to eject ink to complete the printing process.
[0023] The entire digital printing process, including downloading PDF image files, converting to sharp images, and downloading PRN files, is automatically completed by the digital printer ( Figure 7 ), no manual operation is required, which facilitates the use of the machine, saves time and improves efficiency; BRIEF DESCRIPTION OF THE DRAWINGS
